main drawing. (Page Reference: JSGT 5-2)
Define "tare weight" and describe how it is handled when weighing an aircraft. correct
answers Tare weight is the weight of anything on the scales that is not part of the aircraft. It
must be subtracted from the scale weight reading to determine the net weight of the airplane

troubleshooting systems. (Page Reference: JSGT 5-8)
If a piece of equipment such as a radio is added to an aircraft, how can you determine the
effect on weight and balance without re-weighing the aircraft? correct answers If the weight
and balance records are up to date, a new weight and C.G. location can be determined by
computation. (Page Reference: JSGT 6-3)
If the resistance in a DC circuit remains the same but the voltage doubles, what happens to
the amount of current flowing in the circuit? correct answers It also doubles. (Page
Reference: JSGT 3-13)
,Describe an orthographic projection. correct answers It is a way of drawing an object using
different views at right angles to each other, such as a top, front, and side view. (Page
Reference: JSGT 5-10)
Why is control of the weight and balance of an aircraft important? correct answers To
provide maximum safety. (Page Reference: JSGT 6-4)
What is the datum of an aircraft and what is its function? correct answers The datum is an
imaginary vertical plane at right angles to the longitudinal axis of the airplane. It is the
reference point from which all horizontal measurements are taken. (Page Reference: JSGT 6-
4)
Why do manufacturers use symbols on aircraft drawings? correct answers Symbols are a
form of shorthand and are used to convey the characteristics of a component with a minimum
of drawing. (Page Reference: FGH)
In DC circuits, what unit measures power? correct answers Watts. (Page Reference: JSGT 3-
14)
What three elements are required to form an electrical circuit? correct answers A source of
electrical energy, a load or resistance to use the electricity, and wires or conductors to
connect the source to the load. (Page Reference: JSCT 3-15)
Describe the appearance of lines used to show hidden views, alternate positions and the
middle of symmetrical objects, and give their proper name correct answers Hidden views are
shown with hidden lines, which are short, evenly spaced dashes.
Alternate positions are shown with phantom lines made up of light, alternating long dashes
and two short dashes.
Center lines, consisting of alternating long and short dashes, show the middle of symmetrical
objects. (Page Reference: JSGT 5-15)
How do you determine the moment of an item of equipment? correct answers The weight of
the item is multiplied by its arm, which is the distance between the item and the datum. (Page
Reference: JSGT 6-5)
DC circuits can take one of three forms or types. What are they? correct answers Series,
parallel and complex (or series-parallel). (Page Reference: JSCT 3-32)
How can you determine if a drawing has been changed? correct answers A record of the
changes is listed either in a revision block or in ruled columns which may be in a corner of
the drawing or next to the title block. (Page Reference: JSGT 5-18)
What are two ways of determining the arm of an item of equipment? correct answers
Measure the distance between the item and the datum, or use data supplied by the
manufacturer. (Page Reference: FGH)
A 24-volt lead-acid battery has how many cells? correct answers Twelve. (Page Reference:
JSGT 3-66)
, How are dimensions shown on aircraft drawings, and what is their purpose? correct answers
Dimension lines are usually solid and generally broken at the midpoint for insertion of the
measurement. They provide a means to accurately represent the size of an object (Page
Reference: JSGT 5-18)
What should be done to obtain a positive (plus) moment aft of the datum? correct answers
Add weight. (Page Reference: JSGT 6-6)
A fully charged lead-acid battery has a specific gravity that varies between what two values?
correct answers Between 1.275 and 1.300. (Page Reference: JSGT 3-69)
What is the difference between an "allowance" and a "tolerance" correct answers An
allowance is the difference between the nominal dimension and the maximum and minimum
permissible sizes. The tolerance is the difference between the extreme permissible
dimensions, which may be found by adding the plus and minus allowances. (Page Reference:
JSGT 5-16)
What should be done to obtain a negative (minus) moment aft of the datum? correct answers
Remove weight. (Page Reference: JSGT 6-6)
What should be done to obtain a positive (plus) moment forward of the datum? correct
answers Remove Weight (Page Reference: JSCT 6-6)
What is meant by "clearance" when used on aircraft drawings? correct answers An allowable
dimension between two parts. (Page Reference: FGH)
You must apply a correction to the specific gravity reading of the electrolyte of a lead-acid
battery when the temperature is outside of what two values? correct answers Whenever the
temperature is less than 70°F or more than 90°F. (Page Reference: JSGT 3-69)
What is the reason for having separate facilities for storing and servicing nickel-cadmium and
lead-acid batteries? correct answers The electrolyte in the two types of batteries is chemically
opposite and the fumes from one type can contaminate the electrolyte of the other type. (Page
Reference: JSCT 3-73)
What kinds of information about an aircraft drawing can be found in the title block? correct
answers The part or assembly name, drawing size, scale, date, company name, name or
initials of the people responsible for creating or approving the drawing. (Page Reference:
JSGT 5-17)
What should be done to obtain a negative (minus) moment forward of the datum? correct
answers Add weight. (Page Reference: JSCT 6-6)
The state of charge of a nickel-cadmium battery cannot be determined by measuring the
specific gravity of the electrolyte for what reason? correct answers There is no significant
change in the specific gravity of the electrolyte as the battery is charged or discharged. (Page
